4.17-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jason A. Donenfeld <[email protected]> commit dd275caf4a0d9b219fffe49288b6cc33cd564312 upstream. KASAN depends on having access to some of the accounting that SLUB_DEBUG does; without it, there are immediate crashes [1]. So, the natural thing to do is to make KASAN select SLUB_DEBUG.
